High-protein diets have gained popularity, but doctors say more protein is not always better. While protein is essential for building muscle, repairing tissues, and supporting immunity, consuming excessive amounts may not provide additional health benefits and could pose risks for people with kidney disease or diabetes-related kidney damage. Emerging research also suggests that the source of protein matters, with plant-based proteins generally linked to better heart health than processed or red meat. Experts recommend meeting protein needs through a balanced diet that includes pulses, dairy, eggs, fish, lean poultry, soy, nuts, and seeds. The ideal protein intake should be tailored to an individual's age, health, and activity level rather than following one-size-fits-all diet trends.

New research suggests that liver fat, rather than body mass index (BMI), may be a more accurate early predictor of diabetes risk in Asian Indians. The study found that people with prediabetes had nearly twice as much liver and pancreatic fat as healthy individuals, despite having a similar average BMI. Researchers also observed that every 1% increase in liver fat was associated with a significantly higher risk of abnormal blood sugar levels. These findings highlight that harmful fat stored inside organs may develop long before diabetes is diagnosed. Experts recommend focusing on healthy eating, regular physical activity, and early screening to reduce liver fat and lower future diabetes risk.

Beer is often considered a lighter and safer alcoholic drink, but doctors say many popular beliefs about it are misleading. While beer contains small amounts of vitamins and minerals, it is not a health food and does not improve hair growth, prevent weight gain, or make a good post-workout drink. Excessive beer consumption can contribute to abdominal weight gain, disrupt gut health, affect blood sugar levels, and increase the risk of liver disease, heart disease, and certain cancers. Experts emphasize that the health risks depend on the total amount of alcohol consumed rather than the type of drink. If you choose to drink, moderation and hydration remain the healthiest approach.

The U.S. Food and Drug Administration has approved the first mRNA-based influenza vaccine, marking a major advance in flu prevention. Developed by Moderna, the vaccine is initially approved for adults aged 50 years and older. In a clinical trial involving about 40,000 participants, the mRNA flu vaccine reduced influenza cases by 27% compared with a conventional flu shot. Unlike traditional egg-based vaccines, mRNA vaccines can be produced much faster and updated more quickly if circulating flu strains change. Early research also suggests they may trigger a stronger and longer-lasting immune response, offering improved protection during future flu seasons.

A large study involving nearly 4,000 infants has found that the commonly used pain relievers acetaminophen and ibuprofen are equally safe during infancy. Researchers found no evidence that either medication increased the risk of eczema or bronchiolitis, and no serious side effects were linked to their use. The findings provide reassuring evidence for parents and healthcare providers about the short-term safety of these medicines when used appropriately. However, the research is ongoing, and scientists will continue monitoring the children until age six to determine whether either medication has any long-term effects on health or development.

Sitting for long hours each day may quietly harm your joints, muscles, and posture, even if you exercise regularly. Orthopaedic experts explain that joints rely on movement to circulate synovial fluid, which lubricates cartilage and keeps joints functioning smoothly. Prolonged sitting can tighten hip flexors, weaken the glutes and core muscles, and increase stress on the hips, knees, neck, and lower back, leading to stiffness and pain. Experts recommend standing or walking for a few minutes every 30 to 45 minutes, stretching regularly, and maintaining proper posture throughout the day. Frequent movement, combined with regular exercise, is essential for protecting long-term joint health and mobility.

A child who appears healthy and is growing normally may still have hidden vitamin and mineral deficiencies, doctors warn. Persistent tiredness, poor concentration, frequent infections, irritability, weak muscles, brittle nails, slow wound healing, and delayed growth can all be subtle signs of nutritional deficiencies. Iron deficiency may affect learning and memory, while low vitamin D can weaken bones and muscles. Vitamin B12 deficiency may impair development, especially in children on restrictive diets, and zinc deficiency can reduce immunity and appetite. Experts stress that a balanced diet alone may not guarantee adequate nutrition, making regular monitoring and medical advice important for growing children.

Researchers have identified a group of brain cells called orexin neurons that play a key role in maintaining motivation when achieving a reward becomes increasingly challenging. In animal studies, blocking the activity of these neurons reduced the willingness of rats to continue working for rewards, suggesting that orexin neurons help sustain goal-directed behavior. The findings provide new insights into the brain mechanisms underlying motivation and may improve our understanding of conditions such as depression, addiction, and other disorders associated with reduced motivation. However, further research is needed to determine whether these findings translate to humans and could lead to new therapeutic approaches.

New research suggests that exposure to tiny air pollution particles from smoke, soot, and dust may worsen rheumatoid arthritis and increase the risk of painful disease flares. The study found that prolonged exposure to poor air quality may promote inflammation, potentially aggravating joint pain, stiffness, and swelling in people living with the condition. These findings highlight the importance of environmental factors in rheumatoid arthritis management and suggest that monitoring air quality could help reduce flare-ups. Experts recommend limiting outdoor exposure during periods of heavy pollution and adopting strategies to minimize contact with polluted air as part of a comprehensive approach to managing rheumatoid arthritis.

Losing weight is not just about willpower. New research suggests the brain develops a biological "memory" of a higher body weight, making it harder to maintain weight loss. After dieting, the brain can increase hunger, intensify food cravings, and reduce the body's energy expenditure in an effort to restore lost fat stores. This evolutionary survival mechanism helps explain why many people regain weight after losing it. Anti-obesity medications such as Wegovy and Mounjaro may help by suppressing appetite signals, but their benefits can diminish once treatment is stopped. These findings highlight the importance of long-term strategies for sustainable weight management.
